Let us assume capacity of large bottle = 1000 ml.
And capacity of each small bottle = 25 ml.
Reaming milliliters in large bottle = 250 milliliters.
Number of bottles = x bottles.
Total capacity of large bottle - capacity of a small bottle × number of bottles > Reamining milliliters in large bottle.
Therefore, we can setup an inequality.
1000 - 25 × x > 250.
1000 -25x >250.
The rate of Sue is 1 car per hour: 1 (c/h)
then the rate of Steve is 2 (c/h) , because Steve works faster, he can wash twice the number of cars, for the same amount of time.
Thus If Steve and Sue work together, they can wash 1 + 2 = 3
(cars per hour).
That is, the rate of Steve and Sue working together, is 3 (c/h).
In the first 30 minutes, Sue washes half of the car.
The remaining half will be washed at a rate of 3 (c/h)
The main formula is Work = Time * Rate
where Work is washing (1/2)c, and rate is 3(c/h)
Time=Work/Rate =
1/ 6 h =(1/6)*60 min = 10 min
Answer: 10 min
